Bosch R200 E-Bike Range Test Developed as Industry Wide Standard

Laws & Regulations

REUTLINGEN, Germany – Bosch eBike Systems introduced a standard to measure the range of e-bikes with defined parameters. The standard was developed in cooperation with the German industry association ZIV and supported by Accell Group, Shimano, Velotech and the German Institute for Standardization (DIN). With an official DIN publication of R200 forecasted for the end of 2019, it is aimed to serve as a basis for an industry wide standard.

“The standard serves as a tool to create transparency on the market. For the first time, manufacturers, dealers and customers can objectively compare the range of different e-bikes,” states Bosch in a press release.

Important question for many consumers

“How far can I get by with a battery charge? This is an important question for many consumers”, says Claus Fleischer, Managing Director of Bosch eBike Systems. “R200 is a tool for answering that important question. The comparison of e-bike drive systems and providing more information when purchasing an e-bike is extremely important to us.”

ZIV (Zweirad Industry Verband) CEO Siegfried Neuberger adds: “E-bike sales have been rising steadily for years. Therefore, the time has come to define a uniform standard to compare the range of different e-bikes available on the market. We are confident that R200 will be registered at the German Institute for Standardization (DIN) as a formal industry wide standard.”

Standardizing the support factor

R200 compares the performance of e-bikes by standardizing the support factor at 200 percent. The standard parameter is an assumed support factor of a rider performance of 70 watts with 140 watts, which corresponds to a medium to high support factor. R200 also sets parameter for average speed (20 kilometers per hour) and average cadence (60 rotations per minute). Also other factors such as weight, terrain type, surface and wind conditions are set.

Due to different frame and bike specifications, manufacturers need to customize each model individually with the R200 parameters. In addition, R200 provides information on the battery capacity and the energy consumption.

German Velotech and ETI at the Karlsruhe Institute of Technology are both qualified to perform the R200 test.
